Resonant Effects of a Bar on the Galactic Disk Kinematics Perpendicular to Its Plane

open access: yesGalaxies, 2023
Detailed analysis of kinematics of the Milky Way disk in the solar neighborhood based on the GAIA DR3 catalog reveals the existence of peculiarities in the stellar velocity distribution perpendicular to the galactic plane.

The Local Stellar Halo is Not Dominated by a Single Radial Merger Event

open access: yesThe Astrophysical Journal Letters, 2022
We use halo dwarf stars with photometrically determined metallicities that are located within 2 kpc of the Sun to identify local halo substructure. The kinematic properties of these stars do not indicate a single, dominant radial merger event (RME).

A study of radio continuum emission of the Milky Way Galaxy [PDF]

open access: yes, 1996
The synchrotron emissivity distribution of the Milky Way Galaxy has been modelled from the 408 MHz allsky survey of Haslam et al.(1982) after separation of its thermal component with the help of IRAS 60 micron emission(Broadbent et al 1989).

Candidate Members of the VMP/EMP Disk System of the Galaxy from the SkyMapper and SAGES Surveys

open access: yesThe Astrophysical Journal Supplement Series
Photometric stellar surveys now cover a large fraction of the sky, probe to fainter magnitudes than large-scale spectroscopic surveys, and are relatively free from the target selection biases often associated with such studies.

All-sky Kinematics and Chemistry of Monoceros Stellar Overdensity

open access: yesThe Astrophysical Journal, 2023
We explore the kinematic and chemical properties of the Monoceros stellar overdensity by combining data from the Two Micron All Sky Survey, Wide-field Infrared Survey Explorer, APOGEE, and Gaia.

Additional Evidence for the Existence of a Primordial Disk System

open access: yesThe Astrophysical Journal
The origin of very metal-poor (VMP; [Fe/H] ≤ −2.0) stars on planar orbits has been the subject of great attention since their first discovery. However, prior to the release of the Gaia BP/RP (XP) spectra and large photometric samples such as SkyMapper ...

Gas accretion onto the Milky Way

open access: yes, 2017
The Milky Way is surrounded by large amounts of gaseous matter that are slowly being accreted over cosmic timescales to support star formation in the disk.

Numerical simulations of Milky Way galaxies: stellar and gas dynamics [PDF]

open access: yes
Star formation has traditionally been assumed to be a universal process based on observational findings suggesting consistent characteristics across different regions.

The Phase Spiral’s Origin and Evolution: Indications from Its Varying Properties across the Milky Way Disk

open access: yesThe Astrophysical Journal
The phase spiral is a perturbation to the vertical phase-space distribution of stars in the Milky Way disk. We study the phase spiral’s properties and how they vary with spatial position, in order to constrain its origin and evolution, as well as ...
